Wireless Ausculate Educational System / 대한의료정보학회지

This research is about embodiment of system to support auscultation education more effectively. Cardiac sound data that is stored to PC made many learner deliver by wireless system. For this system we developed a special radio transmitter receiver and a program to manage and remake data. Because of selecting radio system, there is no limitation of establishment and education place. also through web server database and update of data are available. For this reason we can add cardiac sound data newly in education. In case of utilizing existent electron stethoscope in auscultation education, the biggest demerit is that do not deliver sense of sound of actuality stethoscope properly. But radio receiving apparatus that we developed is no difference with sense of sound of cardiac through actuality stethoscope and did so that heighten effect of auscultation education.

The Heart Sound Data Analysis, Management System using the Wireless Stethoscope / 대한의료정보학회지

This paper is about the system using a wireless stethoscope to analysis the FFT and the time-frequency for a heart sound and to manage the collected data for a web-based system. We reformed a wireless stethoscope, connected to PC interface and added the analysis function. In result, we combined merits of an existed wireless system to be convenient for measuring the heart sound and to be available for many listener to ausculate the heart sound simultaneously, and an existed wired system to supply the various analysis functions. The heart sounds data was made into the database to search or refer to the patient data. It is possible to search and refer by the web-browser to the recorded heart sound file, the analyzed file by FFT and the STFT time-frequency method.
